Description:
The controller is a thyristor-type power solid state relay designed to control a 3-phase asynchronous motor in two directions. There are two control signals and an internal logic that permits selection of only one direction at a time. A green LED indicates forward; a red LED indicates reverse

Description:
West Control Solutions presents a range of thyristor power controllers which have been designed to switch 2 legs of 3 phase loads. These thyristor units are ideal for 3 phase configuration, resistive load, without neutral connection.
PMA3000 - 2PH = More complex load requirements such as feedback

Description:
West Control Solutions presents a range of thyristor power controllers which have been designed to switch 3 legs of 3 phase loads. These thyristor units are ideal for 3 phase configuration with neutral connection, normal (Relay S or Relay M) or variable resistive loads and transformer load types

Description:
The "WATTCOR W312" thyristor power controllers are designed to control: - standard resistive loads with a low temperature coefficient, - short, wave infrared heaters. - Inductive loads, transformer primaries They can be used in the following cases:
Single-phase: connection of the load

Description:
JW Series is compact lightweight three-phase control thyristor regulators enabling high-density instrumentation. The methods of control are divided into two ways, the phase control and zero-cross control. In the phase control systems, a type with the voltage, current and power feedback control

The pho-
topyrometer 1 maintains the temperature of the
radiating cavity with an accuracy 0.1 K using a three - phase thyristor controller and a temperature
monitor switched into the BB power-supply circuit.

Fortunately, it is not necessary to delve into the waveforms
of three - phase thyristor controllers to gain considerable insight
into harmonics and power factor phenomena, since the single-
phase thyristor controller shown in Fig. 1 has the important
characteristics of all the...

Single- phase thyristor ac controller and three -phase diode rectifier line current waveforms have been
